Bob Brown's last day in office

AFTER 16 years in federal politics, veteran environmental campaigner and Senator Bob Brown spent his last day in office on Friday calling on Antarctica to be World Heritage-listed.

Senator Brown said the "greatest natural heritage property" left on Earth was being denied its rightful place on the World Heritage list.

The former Greens leader called on the Antarctic Treaty 50-member nations meeting in Hobart to give priority to according Antarctic World Heritage status.

"There is no legal impediment. The goodwill of all nations is the vital ingredient to give this logical recognition for the Great White Continent and its surrounding ocean the World Heritage status it deserves," Senator Brown said.
